Electromagnetic Compliance

Electromagnetic compliance information is presented in the following sections:

Electromagnetic Compatibility Regulatory Statements, page ix

Site Wiring Distance and Interference Guidelines, page ix

Electromagnetic Compatibility Regulatory Statements

For regulatory, compliance and safety information, see the Regulatory Compliance and Safety inforamtion for the Cisco 10720 Internet Router document.

Site Wiring Distance and Interference Guidelines

This section offers site wiring guidelines for setting up the site plant wiring and cabling. When planning the location of the new system, consider the following:

Electromagnetic Interference

Electromagnetic interference can occur between the field and the signals on the wires when the wires are run for any significant distance. This fact has two implications for the construction of plant wiring:

Poor wiring practice can result in radio interference emanating from the plant wiring.

Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy and/or cause interference with the signal drivers and receivers in the Cisco 10720 Internet Router, and can create an electrical hazard by conducting power surges through lines and into equipment.

Note To predict and remedy strong EMI, consult experts in radio frequency interference (RFI).

A good quality twisted pair cable or shielded twisted pair cable helps limit radiation and noise induced into the cable minimizing:

Potential for radio interference

Potential for interference with the data transmission.
